Writing letters or patterns on a virtual space by moving a person's gaze is called "eye writing," which is a promising tool for various human-computer interface applications. This paper investigates the use of conventional eye writing recognition algorithms for the purpose of user-independent recognition of eye-written characters. Two algorithms are presented to build the user-independent system: eye-written region extraction using wavelet coefficients and template generation. The experimental results of the proposed system demonstrated that with dynamic positional warping, an F1 score of 79.61% was achieved for 12 eye-written patterns, thereby indicating the possibility of user-independent use of eye writing.

The purpose of this study was to investigate high school students in natural science track and engineering major university students' perceptions about the writing and composition education. A total of 318 high school students in natural science track from two high schools in a metropolitan area and 447 university students majoring in engineering from three universities participated in the survey and asked to response their perceived status and needs of writing education for science-engineering track. The survey instrument, developed by Lee et al.(2009), was used for this study. The data was analyzed through the SPSS 18.0 program for Windows for Multiple Response Frequency Analysis, Descriptive Statistics, Independent Samples t-test, and One-way Analysis of Variance. The results indicated that high school students relatively perceived that writing education was less necessary compared to university students. In addition, high school students found writing less difficult than university students do. In related to studying their experience with writing and composition education, almost no high school students have taken writing classes and university students have taken an average of one class. Most university students who took writing classes took basic writing classes that were not programmed for students in Science and Engineering. In the basic survey to revitalize writing and composition education for Science and Engineering students in different majors, the level of writing and composition education required by students in each major was different. Writing was considered most necessary for students majoring in Chemical Engineering, followed by students majoring in Mechanical Engineering and Electronic Engineering. The study of writing and composition education for high school and college should extend to studies on teachers or professors who teach writing, studies on contents and methods of writing education, and studies on the development of writing programs for different majors in university.

The purpose of this study was (1) to examine the level of learning disabilities reflected in the written expression and writing performance of at-risk children with ADHD, (2) to investigate the level of differences in writing learning disabilities and writing performance depending on ADHD subtypes, and (3) to explore the error types and contents in the written expression of at-risk children with ADHD. The participants in this study were 46 upper grade elementary school children. They were firstly screened by teacher nomination, and only participants with a K-ARS score of over 17 were then selected to be among the 46 children involved in this study. Two further tests were then carried out : K-LDES as an index of learning disabilities in written expression and BASA-writing as an index of writing performance. The results showed that the at-risk children with ADHD possibly had comorbid writing learning disabilities. They were significantly different in terms of the number of total syllables, errors and correct syllables that they produced, in comparison to normal children. But there were no differences as regards the level of learning disabilities in terms of written expression and writing performance based on ADHD subtypes. As regards the implications of these results for future research, we suggested that there is a need for the identification of comorbid writing learning disabilities in ADHD assessment.

Each training was performed five times for two weeks, 30 minutes each time. For measurement, Purdue pegboard was used to look into the change of hand dexterity. To investigate an improvement in hand function through hand function training and writing training, this study conducted early evaluation before training, interim evaluation, and final evaluation. Result : First, according to the comparison of dominant hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved dominant hand dexterity more than the control group. Secondly, according to the comparison of non-dominant hand dexterity by group during a training period, the groups of hand function training and of writing training improved dexterity more than the control group. According to the comparison of non-dominant hand dexterity by method during a training period, there was no big difference in dexterity between the groups of hand function training and of writing training and the control group. But, the group of hand function training showed a further improvement. Thirdly, according to the comparison of both-hand dexterity by group and by method during a training period, the groups of hand function training and of writing training improved both-hand dexterity more than the control group. Fourthly, according to the comparison of both-hand handling ability by group and by method during a training period, the groups of hand function training and of writing training improved both-hand handling ability more than the control group. Conclusion : Given the study result, it is considered that hand function training and writing training help brain damaged patients improve their hand function for their daily activity. And it will be meaningful to research brain damaged patients' motor skills after their brain damage, and the patients who have low abilities of visual perception and cognition. In the future, it will be necessary to secure more study subjects and perform systematic training during a sufficient test period.

The purpose of this study is to suggest a writing education paradigm appropriate for the ideology and ideal persons of Christian universities, and to show the effective application plan. For this, this study utilizes the ideas of digital writing in the concept of digital literacy education. The paradigm of "the digital writing education using bible storytelling" consists of two activities. The first one is 'bible listening and observation,' and the second one is 'media text creation and sharing'. In the first activity, there are two steps: 'listening and observation of bible storytelling' and 'exploration and meditation.' In the second activity, there are also two steps: 'application and action,' and 'sharing in communities.' After the suggestion, this study proposes the application plan for the paradigm. They are 'the utilization of various media and the merit of interaction,' healing effectiveness in an individual and a community,' 'building expertises in both letter writing and Christian education(Divinity),' 'building expertises in both letter writing and media literacy,' and 'expanded application toward diverse patterns of writing.'

For a long time, mathematics education institutions such as NCTM(National Council of Teachers of Mathematics) have emphasized the essential role of writing, and recent surveys by the Ministry of Education report a decline in foundational academic skills in the post-COVID19 period. The purpose of this study is to redefine the significance of mathematics writing in mathematics education, focusing on competencies highlighted in the field, particularly in the areas of problem-solving, communication, and reasoning. The research findings indicate that writing in problem-solving enhances cognitive organization, fostering the ability to grasp concepts and methods. Writing in communication builds confidence through the meta-cognitive process, and writing in inference allows self-awareness of step-by-step identification of areas lacking understanding. Particularly in the future society where artificial intelligence(AI) is utilized, changes in the learning environment necessitate research for the establishment of authenticity judgment through writing and the cultivation of a proper writing culture.
